Thrombectomy is the process by which an intravascular catheter is used to remove or aspirate obstructing particles from the bloodstream. Thrombosis is a disease state that occurs when dislodged blood clots or thrombi block the normal flow of blood through a vessel, causing complications, such as myocardial infarction or stroke. Most thrombi are produced when vulnerable plaque ruptures and the fragments are released into the bloodstream. The intravascular coagulation of blood cells is primarily responsible for the development of thrombi.
